IR Lamps

I have an electrostatic coating business and I would like to change my curing procedure from fuel heated oven to Infrared heated oven but I have a few inquires about the infrared heating lamps ,

1. What type of lamps are used in electrostatic coating ( product name , KW of the lamp )

2. How long does it need to be subjected on the coated metal before the powder melts

3. Does it work like normal lamps and after a while it dies or does it work like microwave halogen lamps goes on whenever you press it on
